Application tiled August 21, 1926. Serial No. 130,670.

plate which is adapted to fit upon or be` fastened to a shaft It is thegeneral object of the invent-ion to provide a simple and improved meansfor mounting the brush proper upon a single plate.V A further object ofthe invention 1sto provide an inexpensive construction whereby the brushproper may be secured or applied to said plate and one which will enablethe brush to be secured to said plate in a quick and convenient manner.

I accomplish the foregoing objects in and through the construction andarrangement or parts shown in the drawing, wherein Fig. 1 represents aside elevation of a brush and plate constructed and assembled inaccordance with my invention; and Fig. 2 a detail in sectioncorresponding to the line 2-2 of Fig. 1.

The brush assembly shown herein Comprises as a whole a central plate 1which ycarries the brush proper consisting of an annular ring havingwires or bristles affixed thereto. The plate is provided with an axialopening 2 therethrough by means of which it and the parts associatedtherewith may be applied and secured to a spindle or shaft. At asuitable distance within and from its periphery. the plate is providedwith an annular rib 3 struck therefrom, the said providing, on theopposite face of the plate, a concave seat 4 for the reception ot theadjacent side and a part of the inner periphery of the brush. The brushcomprises an inner ring 5 which is usually formed by twisting severalwires together, through which wires the bristles or wires 6 are insertedand then folded over so that the ends of the wires or bristles -extendoutwardly or radially, presenting their free or opererating ends to thework to which the brush may be applied.

Struck Jfrom the body of the plate 1, adjacent to and radially inwardlywith respect to the rib 3. are tongues 7. The tongues will be struckfrom the plate 1 so as to extend substantially at right anglestherefrom, as indicated by dot-and-dash lines at 2'a on Fig. 2. Thiswill'enable the ring 5 to be slipped Y over the tongues, until the innerperiphery ot the brush finds the seat 4, afterV which the tongues: willbe bent up into the shape shown in full lines in Fig. 2, so as tocomplement the seat/1 and provide extensions b substantially parallelwith the outer portion of the plate. The brush ring will then be securedagainst the lateral concave part of the seat 4 and will be held inoperative relation thereto and to the annular abutment formed by theinne-r end of the concavity by the tongues 7 The construction describedhereinbefore enables the ordinary type of brush, comprising the bristles6 and the wire-ring 5, to be quickly andl conveniently applied to andclamped upon the plate 1. In the event that it is desired to replace thebrush parts 5 and 6, all that is necessary is to spring the tongues 7substantially to the position shown at 7a, whereupon the old brush partsmay be removed and new ones substituted.

Having thus described my invention, what I claim is 1. A rotary brushcomprising a kplate having an annular rib extending from one sidethereof and located within and spaced from the outer edge thereof,tongues struckfrom said plate and extending in the opposite directionfrom said rib, and a brush member comprising a ring and bristles thereonsecured by said tongues within the concave seat provided within thelsaid rib.

2. A rotary brush comprising a plate having an annular seat formedwithin and spaced from the periphery thereof, a brush member comprisinga ring having bristles thereon and arranged on said seat, and tonguesstruck from the plate and bent to engage the brush member, within thesaid seat, and securing the said member to the said seat.

3. A rotary brush comprising a plate hav- A ing, within and spaced fromthe periphery thereof a seat, a brush member comprising a ring andbristles thereon, and tongues struck from the said plate, within thesaid seat, and bent into engagen'ient with the said member, thereby tosecure the same to said seat.

4. A rotary brush comprising a plate having an annular rib pressedtherefrom, Within and spaced from the outer edge thereof, tongues struckfrom Said plate, Within the said-seat, and extending in the oppositedrection from said rib, and a brush member comprising a ring havingbristles thereon and having one side and part of its inner edgesupported in the concave seat formed by said rib and secured Within saidrib and having its opposite side and inner edge supported by the saidtongues.

In testimony whereof, I hereunto ahX my signature.
